again - some $$ money - not familiar with what type of stipend you would get - it's not the same a fostering though in Ontario but you would immediately qualify for CTB and UCCB if either if the kids are under 6. Something else to consider - there is going to be a new sibling to factor into this - are you willing to take on another baby in order to keep all the siblings together?? If your sister gives her children to CAS (and is threating Bodily harm to them) CAs will like apprehend the new baby and will look to you for placement of that child too - your not obligated but still....
